Title: Regenerative braking for bicycle - has elastomer strip twisted to store energy by friction roller held against tyre
Inventor: KESSELHUT WOLF
IPC: F03G1/04
Filed: 1992-08-13
Abstract: The braking system has two metal friction rollers (8,10) mounted in a housing with a pivot action to bring either one or none of the rollers into contact with the tyre (54).
